Abstract
以'Pollock'油梨为试验材料,在第2次生理落果后采用无纺布袋、白纸袋、牛皮纸袋3种套袋材料对果实进行套袋处理,并定期测定油梨的果实色泽参数、果形指数、果皮色素含量以及果实可溶性糖、可溶性固形物、Vc、脂肪和可溶性蛋白质含量等内外品质指标的变化,探讨不同套袋材料对油梨果实生长发育过程中外观品质和内在品质的影响,为油梨高产优质栽培提供理论依据.结果表明:(1)3种套袋材料均能显著促进油梨果实的生长,显著提升成熟果实的单果重,但对果实生长发育趋势及成熟期无显著影响.(2)无纺布套袋可显著提升油梨果实的果形指数,其余2种套袋材料效果不显著;牛皮纸袋套袋虽能显著增大果实亮度,但会使果皮变黄;白纸袋和无纺布袋可提升果实亮度,但与对照无显著差异.(3)无纺布袋和白纸袋套袋处理可显著提高油梨果皮类胡萝卜素、叶绿素及果肉可溶性糖、可溶性固形物、Vc、脂肪、可溶性蛋白质含量;牛皮纸袋套袋也可显著提高油梨果肉可溶性固形物、可溶性糖、脂肪及可溶性蛋白质含量,但也显著降低了果皮叶绿素含量和果肉Vc含量,并抑制果皮类胡萝卜素的合成积累.(4)各套袋材料还可改变油梨果皮厚度,其中牛皮纸袋可显著提高果皮厚度,无纺布袋和白纸袋则降低果皮厚度,但各材料对果肉密度均无显著性影响.(5)隶属函数法综合分析显示,各套袋处理中以无纺布袋套袋效果最佳,白纸袋次之.研究发现,3种套袋材料均可显著促进油梨果实的生长发育,改善油梨果实的外观品质及内在品质,并且以无纺布套袋综合效果最佳.
Using non-woven bag,white paper bag,kraft paper bag separately covered the'Pollock' avoca-dos after the second physiological drop,we measured regularly the changes of internal and external quality indexes such as fruit color parameters,fruit shape index,and the content of pericarp pigment,soluble sug-ar,soluble solids,Vc,fat,soluble protein.T he purpose is that studies on the effect of different bagging materials on the grow th and development process of avocado fruit in the appearance quality and internal quality.It aims to provide a theoretical basis for high quality cultivation of avocado.The results showed that:(1)the three kinds of bagging materials could significantly promote the grow th of avocado fruit. They significantly increased the single fruit weight of mature fruit,but there is not significant effect on the grow th and development and maturity on avocados.(2)Non-woven bags could significantly improve the fruit shape index of avocados,while the other two bagging materials did not.Although the kraft paper bag could significantly increase the brightness of fruit,but would make the pericarp turn yellow.White paper bags and non-woven bags could increase fruit brightness,but they were not significantly different from the control group.(3)Non-woven bags and paper bag processing could significantly improve carotenoids and chlorophyll in pericarp,soluble sugar,soluble solids,VC,fat and soluble protein contents in pulp of avo-cado.Kraft paper bag also could significantly improve soluble solids,soluble sugar,soluble protein and fat contents in pulp of avocado,w hile reducing the chlorophyll content in pericarp and Vc content in pulp,in-hibition of carotenoid synthesis and accumulation in pericarp.(4)All bagging materials could also change the avocado pericarp thickness.The kraft paper bags could significantly improve the pericarp thickness, while non-woven bags and white paper bags have reduced the pericarp thickness.All bags had no signifi-cant effect on pulp's density.(5)According to the comprehensive analysis of membership function meth-od,the results indicated that non-woven fabric bags are optimum bagging materials,and the white paper bags are the second.These results greatly enriched the suitable bagging materials can significantly promote the avocado's grow th and development,improving the appearance quality and internal quality of avocado fruit.In this experiment,the effect of non-woven bag bagging is the best.
